VCS Requirements for Installing Sybase

Make sure you meet the requirements mentioned here before installing Sybase in a VCS cluster.

Sybase Installation Directory

You can have the Sybase installation directory on a local disk or a shared storage.

• If the Sybase binaries are installed on local disk, verify the installation path is same on all the nodes in the cluster. Make sure the Sybase configuration files are identical on all the nodes in the cluster.
• If the Sybase binaries are installed on shared disks, make sure the mount points for the shared disks are same on all the nodes. The Sybase installation directory is specified by the environment variable $SYBASE. Create the same $SYBASE mount points on each system.

$SYBASE Directory on Shared Disks

All database devices, including master devices, sybsystemprocs, and information about Sybase user must be located on shared disks. If the database devices are created on file systems, the file systems must also be located on shared disks. Create the same file system mount points on each system to access the shared disks.
